8 cm A right cylindrical solid is cut in half to form the figure
shown. If the length is 20 cm and the diameter is 8 cm,
what is the surface area?
20 cm
A(807 + 160) cm2
B(967 + 160) cm2
C3207 cm2
D(3207 + 160) cm

b 96 plus 160 cm

Step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

no
